Based on your description of wave A and wave B:
- Wave A has a certain distance along the horizontal line between two consecutive crests (wavelength).
- Wave B has a shorter distance along the horizontal line between consecutive crests compared to wave A, which indicates that wave B has a shorter wavelength.
- Since frequency is inversely related to wavelength (shorter wavelength = higher frequency), wave B would therefore have a greater frequency than wave A.
Thus, the correct completion of the statement is:
shorter wavelength and greater frequency.
